I have been using Denver House Cleaning Company for a while now, and I find that their service really varies. I appreciate that whenever I have problems, the company is quick to respond! I also like that they are really flexible with hours and when I need to make a change of my schedule, they work around me. I appreciate that they always have lots of people available, so you are never worried about finding someone. However, sometimes they don't pay as close attention to detail as I would like. For example, when they clean my microwave, they often do not put it back together correctly so I have to go back in later and fix it. It is small things like that that can frustrate me, but it isn't frustrating enough to stop using them. If you are thinking about using them, I would mention that they are really friendly, but just be prepared to potentially have to look over their work.
